In my application I use a SAFT lithium battery (LS 26500). I'd like to detect it's end of live by measuring voltage value. The voltage value depends on current and temperature.
So, I'd like read the temperature from the accelerater sensor on my board.
The problem is that I saw this thread : LIS2DH12 Temperature readings
If I understand, the temperature value is not absolute. So, my question is :
- How do I calibrate the temperature sensor ?
- What is the conversion factor to get the right temp value?
